Abstract

Two classes of FIR-median hybrid (FMH) filters are introduced, which are called in-place growing FIR-median hybrid (IPG-FMH) and recursive in-place growing FIR-median hybrid (RIPG-FMH) filters. This new extended family of filters exhibits a very small bias error in the vicinity of an edge, an yet provides good noise attenuation. It is shown that the IPG-FMH filters can be expressed as weighted FMH (WFMH) filters. >
